Plugged

Howard County · Howard-Glasscock (Wolfcamp 7400) field · Vertical

Chalk Owen #43 (API 42-227-33906) is a plugged well in Howard County, plugged May 22, 1996, last operated by Citation Oil & Gas Corp..

The RRC has issued one drilling permit, issued November 7, 1985, permitted to 8,500 ft.

It was permitted by Mobil Producing TX. & N.M. Inc. and has since transferred to Citation Oil & Gas Corp. on the wellbore schedule.

Completion filings report 8 formation tops, including Yates, Seven Rivers, Queen, San Andres.

Its lease has reported 34.7K barrels of oil and 156K mcf of gas since the record begins in January 1993, with no volume in the three years through August 2026. The lease carries 7 wells, so these are lease totals, not this well alone.
